How to use Spring Boot BOM, instead of parent?


I need to use BOMs in my project, so simplify the task of managing dependencies. This is the requirement, I cannot pivot at this stage.

I removed parent spring-boot and added AWS, Spring Boot and Junit5 as BOMs. The issue is, even though I have them, dependencies aren't downloaded correctly. Am I missing some plugins or I am doing something else wrong?

I have tried:

All of the above worked correctly. The issues I am getting after adding BOMs are:

package org.junit.jupiter.api does not exist
package org.mockito does not exist
cannot find symbol
[ERROR]   symbol: class ExtendWith

Am I understanding BOM concept wrong? Why are there no dependencies, even though they are declared in pom.xml? How can I run this code without parent but with BOM?


Solution

  • The issue I had, was related to a misconfiguration in pom.xml

    Instead of

    <sourceDirectory>${project.basedir}</sourceDirectory>
    

    I have to use

    <sourceDirectory>${project.basedir}/src/main</sourceDirectory>
    

    This said, it is possible to package differently from pom packaging, so I can use jar or other alternatives.
